STUART A. STANDIFORD, OF LANCASTER, PENNSYLVANIA MACHINE FOR MAKING SPIKES.

SPECIFICATION forming part of Letters Patent No. 250,595, dated December 6, 1881. Application filed July 8,1881. (ModeL) To all whom it may concern:

Be it known that I, STUART A. STANDIFORD,

vof Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain 5 useful Improvements in Spike-Machines, of

which the following is a specification.

My improvements relate to machines for forming spikes from a continuous bar or red; and the invention consists in certain novel features ofconstruotion and combinations ofmechanism, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of the machine. Fig. 2 is a side elevation of the same. Fig.3 is a transverse section on line wot Fig. 2. Fig.4is a crosssection on line y y of Fig. 2, and end view of the head-block and pointing-levers. Fig. 5 is a cross-section on line .2 z of Fig. 2. Fig. 6 is a sectional plan view of the head-block on line 10 w of Fig. 4, and Fig. 7 is a cross-section of the header.

Similar letters of reference indicate corresponding parts.

A is the bed of the machine, across one end of which is the operating-shaft a, supported on plumber-blocks b. Lengthwise of the bed is a V-shaped groove or slideway, 0, in which is a slide, B, provided with a crank-pin, cl, and a rod, 6, from an eccentric, f, on shaft 0, is connected to the crank-pin d. As shown most clearly in Figs. 1 and 3,the slide B is recessed atits mid-length to give space for a fixed post, g, which carries the jaw h of the clamp. The bed is slotted crosswise from the post 9, to receive a slide, 2 which carries the other jaw, h, of the clamp. The inward movement of this slide is given by a bent lever, k, hung beneath bed A,which is connected by one end to slide t, and at the other end connects toaslide-block, Z, that has an arm, Z, extending upward in front of a cam, m, on shaft a. A spring, a, connecting by a rod, 0, to the lever it, retains the-arm l in contact with the cam and opens the clamps. On the outer end of the slide B a head, 0, is attached by a screw, a, the screw passing through a slot to allow endwise adjustment of the head. Upon the head, and lengthwise of the same, two levers, p p, are hung, the inner ends of which carry rolls 12 At the rear end of the head a rock-shaft,

q, carrying cams q q, is fitted crosswise, so

that the cams engage the ends of levers p at the inner sides. Springs r r, attached to the head 0 and bearing on the outer sides of the levers, tend to force the levers together and open the rolls p.

Between the inner ends of levers p the head 0 is provided with a fixed cutter, s; and in a bridge above is a sliding cutter, t, carried by a plunger, a, to which the cutter is held by a screw and nut, so as to be adjustable. The plunger a is in an aperture crosswise of head 0, and is forced down by devices hereinafter described, and raised by a spring, a".

The inner end of slide B is fitted with ablock, D, to which the head-forming die n is fixed. The block D is attached rigidly to a plate, '0 and the plate is attached to slide 13 by screws passing through slots in the plate, so that the block may move endwise of the slide. A setscrew, a, sustained on bed A by a lug, a arrests the backward movement of the block D, and thus by positioning the forward end of header o regulates the length of material for forming the head.

For the operation of the cutters and movement of levers p the bed A carries a rockshaft, 12, sustained in bearings 12 b at the side of the head 0. On this shaft is fixed acollar, 0, formed with a shouldered portion, 0 see Fig. 4,) that projects above a shoulder, d, formed on the plunger 10. On the inner end of shaft 1) is an arm, 0, having a side lug or projection, e that extends above a beveled extension, f, of the slide i. An arm, 9 on the cam-shaft q of levers carries a link, 11. which extends at the side of shaft 1), and the inner end of the link is bentoutward to take behind the shoulder c of the collar 0. (See Figs. 4 and 6.)

In the operation of the machine the first position is that shown in Fig. 1, with the head 0 moved inward, block D outward, slide 6 outward, and the clamps h It thus opened. The spike-rod is entered from the back end of head 0, through between the rolls 19 11 and clamps h h, with its end taking against the header awhich, being positioned by the screw a, regulates the projection of the rod beyond the clamps. The length of the spike between the head and point is regulated by adjustment of head O on slide B, and the arm 0 on shaft 1), with reference to the bevel f of slide 1'. The shaft to, first acting by cam m on the slide 1, moves slide z inward, and the rod is clamped by the clamps h h. At the same time the extension f, acting on the arm 6, gives a partial revolution to shaft 1), and the collar 0 coming down upon the plunger a, the cutter t is forced down to cut oft the rod. This movement of shaft 1) also brings the shoulder c in front of the bent end of link If, thus locking the cam-shaft q. The slide B, now movingoutward, carries block D inward, and the header-die V compresses the head of the spike. The head 0 is at the same time carried outward, and the link ]L2 being locked, the cam-shaft q is caused to turn, and the cams, acting on levers 1), press the rolls p on the end of the spike until the rolls meet, and thus form a wedge-shaped point. As soon as the back-stroke of head 0 is completed the clamps h it open, the spike drops out, and the slide B then returns to the first position. A completed spike is shown in Fig. 9.

To prevent a pin being formed on the point when rolled the cutterss t are shaped as shown in Fig. 8, to compress the spike at right angles to the subsequent rolling operation.

Having thus described my invention, I claim as new and desire to secure by Letters Paten t- 1. In spike-machines, the reciprocating slide B, head 0, carrying the cutters and pointing mechanism, block D, carrying the heading-die, and the clamping devices, substantially as shown and described, combined for operation as set forth.

2. The combination of slide B, head (3, carryin g the cutters and pointing mechanism, block D, carrying the heading-die, slide 17, carrying the clamping-jaw, and the rock-shaft b, actuated by the slide for operation of the cutters and pointers, substantially as shown and described.

3. The levers p, rolls p double-cam shaft q, arm g and link 71?, combined with the reciprocating head 0, and rock-shaft I), provided with shouldered collar 0, substantially as shown and described, for operation as set forth.

4. The sliding cutter t, plunger a, and fixed cutters, combined with the reciprocating head 0, substantially as shown and described.

5. The head 0, fixed cutter s, cutter t, plunger a, and rock-shaft I), provided with the shouldered collar 0, substantially as shown and described, combined for operation as set forth.

6. The combination of slide 2', provided with beveled extension f, shaft 1), provided with arm a, and collar 0, plunger a, cutter t, and head 0, substantially as shown and described, for operation as set forth.

7. The combination, with the clamping slide 2', of bent lever 7c, slide-block l, and the cam m on shaft a, substantially as shown and described.

8. The combination of block D, carryingthe header, movable plate '0 and the fixed screw a, with the reciprocating slide B, substantially as shown and described.

9. The block D, header o, and reciprocating slide B, combined with the clamping-jaws h 71/, substantially as shown and described.
